Loss on tendered notes

During 2013, we recognized a loss related to the extinguishment of debt in connection with the tender offer on our 9.25% senior notes. See Note 13—Debt for additional discussion. In 2013, we completed a cash tender offer for these notes and repurchased $785.4 million aggregate principal amount. We paid the holders an aggregate of approximately $1.0 billion in cash, reflecting principal and accrued and unpaid interest and recognized a loss as part of the debt extinguishment.

Provision for retirement of long-lived assets

During 2013, we recorded a provision for retirement of long-lived assets in multiple operating segments totaling $14.0 million, which reduced the carrying value of some assets to their salvage value. The retirements related to assets in Saudi Arabia and included obsolete top-drives, nonworking trucks, generators, engines and other miscellaneous equipment. The retirements in our Canada operations included functionally inoperable rigs and other drilling equipment. In our Completion & Production operations, the retirements related to rigs and vehicles that would require significant repair to return to work and other non-core assets.

During 2012, we recorded a provision for retirement of long-lived assets in multiple operating segments, including $37.1 million in U.S., $33.7 million in Canada, $16.5 million in International and $2.0 million in Rig Services, all from our Drilling & Rig Services business line. The retirements in this business line included mechanical rigs, a jackup rig and other assets that have become inoperable or functionally obsolete and that we do not believe could be returned to service without significant costs to refurbish.

Additionally in 2012, we recorded similar provisions for retirement of long-lived assets of $49.4 million in our Completion & Production Services business line. During 2012, we streamlined our operations and consolidated our Completion & Production Services into this business line, and retired some non-core assets. As we continue to streamline our lines of business, there could be future retirement or impairment charges, which could have a potential impact on our future operating results.

During 2011, we recorded a provision for retirement of long-lived assets totaling $98.1 million in multiple operating segments. This related to the decommissioning and retirement of one jackup rig, 116 land rigs, and a number of rigs and trucks. Our U.S., International and Production Services operations recorded $63.2 million, $26.1 million and $8.9 million, respectively. These assets were deemed to be functionally or economically non-competitive for today's market and are being dismantled for parts and scrap.

A continued period of lower oil and natural gas prices and their potential impact on our utilization and dayrates could result in the recognition of future impairment charges to additional assets if future cash flow estimates, based upon information then available to management, indicate that the carrying value of those assets may not be recoverable.

Impairments of long-lived assets

During 2013, we recognized an impairment of $20.0 million to our fleet of coil-tubing units in our Completion & Production Services business line. Intense competition and oversupply of equipment has led to lower utilization and margins for this product line. When these factors were considered as part of our annual impairment tests on long-lived assets, the sum of the estimated future cash flows, on an undiscounted basis, was less than the carrying amount of these assets. The estimated fair values of these assets were calculated using discounted cash flow models involving assumptions based on our utilization of the assets, revenues and direct costs, capital expenditures and working capital requirements. We believe the fair value estimated for purposes of these tests represents a Level 3 fair value measurement. In 2013, we suspended our coil-tubing operations in the United States. A prolonged period of slow economic recovery could continue to adversely affect the demand for and prices of our services, which could result in future impairment charges for other reporting units due to the potential impact on our estimate of our future operating results.

During the fourth quarter of 2012, we determined that some of our coil-tubing rigs would not be fully utilized as forecasted, which resulted in a triggering event and required a year-end long-lived asset impairment test. Our year-end impairment test resulted in impairment charges of $17.4 million in our U.S. and $32.9 million in our Canada operations.

We did not record any impairment of long-lived assets in 2011.

Provision for termination of employment contract

During 2013, we recognized a one-time stock grant valued at $27.0 million, which vested immediately, and $18.0 million in cash awarded and paid to Mr. Petrello in connection with the termination of his prior employment agreement. See Note 19—Commitments and Contingencies for additional discussion.

During 2011, we recorded a provision for a contingent liability that existed on December 31, 2011 related to the change of our Chief Executive Officer that occurred in October 2011. This charge resulted from a potential termination payment to our former Chief Executive Officer, Eugene Isenberg, under the terms of his employment contract. Subsequent to December 31, 2011, Mr. Isenberg elected to forego triggering that payment and as a result, we did not owe or make the termination payment. During 2012, we made charitable contributions to benefit the needs of our employees and other community-based causes. We contributed one million Nabors' common shares previously held by an affiliate to the Nabors Charitable Foundation, a 501(c)(3) organization, in support of this objective. We consider our former Chief Executive Officer to be a significant shareholder of the Company and, therefore, recorded these transactions as equity. During 2012, we recorded the release of the contingent liability, net of tax, through capital in excess of par as a forgiveness of liability from a beneficial owner. We recorded the donation of the treasury shares at their weighted-average cost, net of tax, through capital in excess of par.

Intangible asset impairment

During 2012, we recorded an impairment of the Superior trade name totaling $75.0 million. The Superior trade name was initially classified as a ten-year intangible asset at the date of acquisition in September 2010. The impairment is a result of the decision to cease using the Superior trade name to reduce confusion in the marketplace and enhance the Nabors brand.

There were no intangible asset impairments in 2013 or 2011.

Goodwill impairments

During 2012, we recognized the impairment of goodwill associated with our operations in the U.S. and International drilling operations. The impairments were deemed necessary due to the prolonged uncertainty of utilization of some of our rigs as a result of changes in our customers' plans for future drilling operations in the Gulf of Mexico as well as our international markets. A prolonged period of lower natural gas prices or changes in laws and regulations could continue to adversely affect the demand for and prices of our services, which could result in future goodwill impairment charges for other reporting units due to the potential impact on our estimate of future operating results.

There were no goodwill impairments in 2013 or 2011.
